itemInfoAtTheta

Calculates item information at a value of theta given a set of item parameters for one item.

Extends 'ACER ConQuest' through a family of functions
designed to improve graphical outputs and help with advanced analysis
(e.g., differential item functioning). Allows R users to call
'ACER ConQuest' from within R and read 'ACER ConQuest' System Files
(generated by the command `put` <https://conquestmanual.acer.org/s4-00.html#put>).
Requires 'ACER ConQuest' version 5.40 or later.
A demonstration version can be downloaded from <https://shop.acer.org/acer-conquest-5.html>.
